Occupy Pepper Spray

In this Nov. 18, 2011, file photo, University of California, Davis Police Lt. John Pike uses pepper spray to pressure Occupy UC Davis protesters while blocking their exit from the school's quad in Davis, California. Parts of a report on the pepper-spraying by campus police of student demonstrators will remain under seal while a judge decides if releasing the material would impact officers' privacy, according to a ruling by Superior Court Judge Evelio Grillo on Friday, March 16, 2012.
